Abstract
An external combustion engine including a containersealed with a working mediumin liquid phase adapted to flow, a multiplicity of evaporatorstofor heating and evaporating part of the liquid-phase working medium, a multiplicity of condenserstofor cooling and condensing the working mediumevaporated in the evaporatorsto, and an output unitfor outputting by converting the displacement of the liquid-phase portion of the working mediuminto mechanical energy. The multiplicity of the evaporatorstoshare a heat source from which heat is supplied thereto. The engine further includes an influent liquid amount regulation unit whereby the liquid-phase portion of the working mediumin a greater amount flows into the evaporators nearer the heat source upon displacement of the liquid-phase portion of the working mediumtoward the multiplicity of the evaporatorstofrom the output unit, while the influent liquid amount is smaller for the evaporators farther from the heat source. In this way, heat loss is reduced resulting in improved efficiency.
